You do not need an amateur on the job when you are in the marketplace for mechanical engineering services. That isn’t a game; you want a mechanical engineer who understands the tricks of the trade, although not only the principles.
But the essentials of machinebouw are nothing to sneeze at. You are in need of a mechanical engineer who will not seem baffled when you talk about the conservation of momentum, or when he needs to make unit conversions.
So, with that in your mind, here are questions to springtime during a preliminary interview on a mechanical engineer.
How you can find about the mass of the apple? Be sure to have an apple when asking this question. Be sure to change the wording of your question, If you just have an orange. You do not need your mechanical engineer believing you are a weirdo. But if he does, telling you the way to discover mass should not be overly difficult. Just put the apple quantifies the resultant oscillation of the springs, and to oscillate between some of springs in a weightless environment. Needless to say, IF you not have a correctly calibrated set of mass-measuring springs, or a weightless environment, you could put the item in a scale for quantifying mass designed.
Is acceleration a vector or a scalar amount quantity?
A good mechanical engineer understands his scalars and vectors. He also understands that acceleration (a change in the speed of an item) is a vector quantity. That means it got two independent variables: magnitude and Direction. Their amounts muse be depicted on a graph. Scalars just have one measurement, as well as their amounts may be depicted on a line.
